“…1b ). This shift has been correlated to the substitution of the smaller Ti 4+ ions (ionic radius = 0.061 nm) into the larger Fe 3+ ions (ionic radius = 0.069 nm) of Fe 2 O 3 (Hwang and Jung 2022 ) (Fig. 1b ).…”

In this work, Ti-doped Fe2O3 with hollow ellipsoidal capsules nanostructure has been prepared in a green manner using plant extract (flax seed). This new green hematite nanomaterial has been evaluated as photocatalyst for water treatment by testing its activity for degradation of bromophenol blue dye (BPB) and 2,4-dichlorophenoxy acetic acid (2,4-D) herbicide. For a better understanding of the green material properties, a comparison with the pristine Fe2O3 nanospheres previously prepared by the same procedure is included. Structural and optical properties of the green prepared materials are studied. The results revealed the success doping of Ti4+ at Fe3+ site, without forming any of TiO2 phases. It was also found that the Ti doping resulted in the reduction of the band gap of Fe2O3 as well as changing the morphology. The Ti-doped Fe2O3 nanomaterial exhibited an enhanced photocatalytic activity either for BPB dye or for 2,4-D degradation with more than 2 times higher rate than that using pristine Fe2O3.
